ANTISKIDDING DEVICE FOR DUAL TIRES.

Application filed October 28, 1921.. Serial Ne. 511596.

Te all whom it may concem:

Be it known that I, WALTER LION, a subject of the Republic of Prussia, German Republic, and resident of Dresden N, have' inv'ented a new and useful Improvement in' against displacement within thelinks of the chain and permits a slight movement of the tread in the link and on the tres.

The Construction and arrangement 'of the metal treads admits of easy and rapid insertion and removal, and the number of treads may be increased or reduced as desired.

Another object is to provide certain improvements in the form, construction and arrangement of the parts, whereby .the above named and otherobjects may be eifectively attained. i

A practical embodim'ent of my invention is represented in the accompanying drawing, in which F ig. l is a vertical section through the periphery of a dual and hard rubber-tire. Fig. 2 is a plan of a separate metal tread or gripping plate inserted into a chain-link and Fig. 3 a section at aright angle to Fig In Fig. 1 of the drawing, I have shown a chain having links denoted by Z located between dual elastic tires (r of hard or solid rubber, arranged side by Side. ping or anti-skidding devices are each to move on the tires and -in' the'links.

chain, as desired.

The gripformed of a. metal rtread a provided with a longitudinally arranged reinforcing rib c and a transverse groove or notch'c which is arranged to coact with one of the'vertically disposed links bof the chain. device is in position, the outer ends of the with the links of the 'chaintdisposed between the tires, in which position tension is placed upon the chain by means of tension links (not shown) and the treads held against displacement in the links of the chain and in'contact with the tii-es. `By this construction, it will be seen that the treads are free It will also 'be seen that the outer edge of the substantially in' alinem'ent with the perphsurfaces of the tread, and so assist thetrea'ds n p resenting an addtional resistant element to the device.` I

It will be understood that any numberof,

the links of the.

treads may be inserted in What I claim is:

l. An anti-skidding'device :for dualtires having in combination a 'chain disposed between the tircs and metal treads loosely mounted in ;the links and held in contact with the tircs. i e i 2. An anti-skidding device for dual tircs When the tread rest upon the periphery of the tires a I vertical links of the chainwill 'be brought a .ery of 'the tires and thejonter or contact havingin combinartiona chain disposed bei tween th'e tires and metal treads loosely mounted in the links and held in contact with the tires, said treads having grooves arranged to ,coa'c with'the links of the chain.

In' testimonyrthat I claim the foregoing i :as my nvention, I have signed my name 'this 28th day of Oc ober, 1922.
